all whom it may concern.

Be it known that l, Jenn A. Wiinonf citizen of the United States,residing at Golumbus. in the county of Cherokee and State of Kansas,have invented newra nd useful Improvements in Bedstezids. of wbich thefollowing is a specification,

The general object of the invention is to provide at bed that may belmockeddown and folded into a con'ipnrntively small co1npass when not inuse.

Other objects will appear and be better understood from the followingdescription taken n connection with the accompanying in which,

times comprising the side end end mils are of uniform size-in crosssection, and also the sections 5 and 6 move in a direction when foldingone upon the other at right angles tothe direction in which the siderails move when folding one upon the other and on to the end mils. Itwill be also observed that the side rails are of different lengths andat the juncture of the side and'end rails angular shaped brackets t9iireprovided which are herein shown as Secured to the end rails andconnected by the pivots 8, before stated, to the side rails. lit will beobserved that the brackets connecting the shorter side rail with the endrails ere longer than the opposite brackets connecting the longer siderail, the length of the longer brackets being 5511f.- ficient to permitthe shorter side rail to be folded on to the longer when folded on tothe end rails es; shown. iirFig. 6.

The supporting legs 0 arranged at the opposite ends and middle bed, theloge 10 at the foot end of the bed being herein shown as angular incross section and pivoted to the foot mi! and foldable on to the latter.Suitable latches 11 are pivoted to the legs 10 and are adopted tointerlock with keepers 12 end cooperate with. the same to hold the legs10 against movement when the bed is set up and ready for use.'

The middle-legs 13 are herein shown as angular and pii'oted to andadapted to be folded onto the side rails. Suitable latches with keepersprevent m0ve- 13 being accomplishedin any suitable mo nor such as bystuds 17 arranged at tne op};

stops 18 are arranged on the bar 16 end adapted to bear .on the adjacentedges of the legs; 13, and latches 19 herein shown. as pivotedjtothe/Stops 18 and movable over one face of tlielegs 13 when the'berconnect thereto whereby to prevent "uccii den. t displacement of the barthe latter is i when the bed is set up og connection betweentbebar'lfiand 1e posite' ends of tl cfbur, 1 6 and edapted toenteropenings in thelege l3. Suitable portion of the latcafrried by one ofthe sections of'the side ctr-lie side sections Clio - The legs 20 at thehead end of the bed are herein shown as pivotally connected to andadapted to told on to the head rail when. the bed has beenfolded aspreviously described. In order to prevent folding of the legs when thebed is set up I make use of a headpiece herein shown to consist ofdepending portions 21 connected at their upper ends by a. crosapicce andhaving ofi'set portions 23 at their lower ends provided with studs 24received by bayonet slots in the legs 20. The cross-bar 22 is pivoted tothe portions 21 whereby the latter may be folded on to the former whennot in use. The portions 21 are adapted to interlock with the head railin any preferred manner such as by means of studs having shank portions26 adapted to enter notches 27 in the head rail, the cross-piece 22 isalso adapted to interlock with the head rail in any preferred mannersuch as by means of a latch 28 adapted to engage a keeper '29 carried bythe head rail.

It will be observed that the -le s are formed with shoulder 30which'bsar on the side and end rails whereby the-tweight of the parts isnot thrown on to tliepivots of the legs. V y

In connection with the bed just described I make use of the spring 31.The body of this element comprises a plurality ofi links 32 arranged endto end and connected by eyes. 83 the eyes being in turn connected bycross-links 34. The body is connected to the end bars 35 and 36 by meansof retractile springs' 'i-l7 and the bars and 36 are adapted tointerlock with hooks 38 and 39 secured, to the end rails as shown. Thebars 35 and 36 have recesses 40 which receive the bills of the hooks 138and 39 and the said bars are herein shown as corresponding substantiallyin width to the horizontal side portions of the end rails so that inorder to connect the bars with tlije hooks it is necessary to slightlytilt the same in order that the bills of the hooks may enter therecesses of the bars. In order to prevent accidental engagementbetweenthe bars and hooks T make use of a locking device one embodiment ofwhich is herein shown to consist: of lovers 4) pivoted to the end railsand adapted to be moved outwardly and under clips 4.3 carried by thebars 35 and 36 after engagement between the latter and the "hooks hasbeen efi'ectcd. With this construction it. will be seen that when thelevers and clips hear one upon the other it will be impossible to tiltthe bars sutiiciently to disengage the same from the hooks.

The spring previously described is somewhat less in length than thedistance between the hooks at the opposite end rails and one methodoftensioning the spring mnsists in first connecting one of the bars withthe hooks of one end rail and then partly folding the side rails so asto bring the hooks of the opposite end rail nearer to the hooks of thefirst named end rail in which position the other bar may be readilyconnected to the hooks and lock as previously described, after which thesections may be moved. into alinement whereupon the spring will betensioncd.

Assuming that the bed has been set 11 and it is desired to fold the samethe hca piece is first removed by disengaging the latch 28 with thekeeper 29, after which the head-piece is moved upwardly in the bayonetslots 25 until the portions 21 may be moved inwardly and out ofengagement with the side slots whereupon the head-piece may be removed.The latches 14 are then disengaged from the middle legs 13 whereupon thesections of the side rails may be partly folded thus removing thetension on the spring and permitting the same to be detached from thehooks which may be accomplished first by moving the levers 42 fromengagement with the members 43. When the spring has been removed thesections 5 and 6 of each side rail are folded one upon the other, afterwhich the legs are folded on to the side and end rails, it beingunderstood that the latches of the foot end legs are first disengagedfrom their keepers. When this has been done the parts will be positionedas shown in Fig. 7 after which the side rails may be folded one upon theother as previously described whereupon the entire structure when foldedwill be of no greater length than one of the end rails. By virtue of theflexibility of the spring the latter may be wrapped around the foldedbed and the whole packed into a 105 small box or receptacle.

From the foregoing it will be seen that the device is exceedingly simplein structure and has a minimum of parts and is particularly adapted foruse in camps, 110 households, etc.

Although I. have shown and described one vform of the device it is to heunderstood that I am not to be limited to this specific structure andarrangement of parts since 11.5 various changes may be made, in thescope of the appendwl claims without departing from the spirit orsacrificing any of the advantages of the invention.
